Abstract: 148,465. International Moving Picture & Film Co., (Assignees of Hunt, J. R.). Feb. 18, 1919, [Convention date]. Kinematograph apparatus.-Relates to kinematograph projectors of the kind in which, to avoid flicker, a single film passes over two display apertures, functioning alternately, feeding means near each aperture being driven by separate rackoperated ratchet mechanism. A rack plate with a rack across each end is reciprocated widthwise between the two feeding-means to drive them alternately. The film is provided with two sets of pictures, each set being projected through a particular aperture, and the pictures are numbered as indicated in Fig. 5 in order to facilitate the correct placing of the film in the machine. A casing 30, Fig. 1, is provided with two light-receiving apertures 31, 32, in front of each of which are the usual aperture-plate 60 and presser-gate 61. The film 25 is fed to the upper aperture-plate 60 by means of a sprocket-wheel 62 secured to a shaft 63. The shaft 63 is provided with a ratchetwheel 64, the pawl 65 of which is mounted upon a loose gear-wheel 66 rotated by the rack 67 of a plate 68. The plate 68 is oscillated by a cam 80 mounted upon a shaft 81 and rotating in a rectangular aperture in the plate 68. The shaft 81 is operated through worm-gearing 82, 83 from a power shaft 46. The film 25 is fed to the lower aperture-plate 60 by a similar mechanism, the arrangement being such that while the plate 68 is moving from left to right the film is fed to the lower aperture-plate, and while it is moving from right to left the film is fed to the upper apertureplate. A semi-circular shutter 90 rotates in front of the projecting lenses 33 and 34 to intercept the beams in front of each lens while the film portion behind the lens is in motion. The beginning of the film 25, Fig. 5, is provided with an odd-numbered set of pictures separated by blanks, and the first even-numbered picture is placed after the eleventh picture on the film, after which the pictures are numbered alternately odd and even. The feed mechanism of the film is such that the oddnumbered pictures are projected through the lower lens 34, Fig. 1, and the even-numbered pictures are projected through the upper 'lens 33.

Abstract: 1,248,276. Spray carburetters. TOYOTA JIDOSHA KOGYO K.K. April 22, 1969 [April 23, 1968], No.20587/69. Heading F1B. A carburetter for an I. C. engine, having an idling and slow-running circuit 9, Fig. 1, has a valve-controlled additional circuit 24a, 24b which supplies additional mixture to avoid misfiring of the engine during rapid deceleration thereof. The circuit 9 comprises air bleeds 7, 11, a fuel jet 10 and an economizer jet 12, and has a slow-running slit 8 and an adjustable idling port 13. The valve 31 in the circuit 24a, 24b is normally closed by an adjustable spring 39, but is opened by a diaphragm 33 when a high vacuum is created in the intake manifold 40 due to rapid decelerations of the engine. The circuit 24a, 24b has bleeds 17, 19 and jets 16, 18 similar to the circuit 9. When the valve 31 is opened air passes through the circuit 24a, 24b from an adjustable inlet 21 fowards an outlet 22 downstream of the throttle valve 6. Thus mixture is drawn from a passage 26 via an adjustable valve 27 into the air-flow, and the resulting mixture passes through the outlet 22 to the inlet manifold to supplement the mixture supplied from the circuit 9. The inlet 21 may be formed by a tube (21<SP>1</SP>), Fig. 2 (not shown), projecting upwardly and inwardly into the intake passage 2. In an alternative embodiment, Fig. 3 (not shown), the valve (23<SP>1</SP>) in the circuit (24a, 24b) is of the electromagnetically-actuated type energized and thereby opened by a battery (42) through a diaphragm-actuated switch (41) which is closed when high vacuum occurs in the intake manifold to which it is attached. The electrical circuit includes a light (46) which indicates when the valve (23<SP>1</SP>) is open. Many of the parts of this latter embodiment may be mounted separately of the carburetter.

Title: Computer data storage system
IPC: G06F7/02
Filed: 1964-05-21
Abstract: 1,018,915. Electric digital data-storage INTERNATIONAL BUSINESS MACHINES CORPORATION. May 21, 1964 [May 23, 1963], No. 20948/64. Heading G4C. In a binary data storage system for hierarchically-organized data of variable field length and having identifier symbols separating the levels of data, the location of identifier symbols in a main store in which a data string is stored is specified by occurrence marks in an auxiliary store. In the particular embodiment, a data string consisting of 8-bit characters is stored in the form of 8-character words in a 3-dimensional magnetic core matrix main store. The data is considered to be organized according to a hierarchy of levels, e.g. phrase, sentence, paragraph, and the beginnings and ends of phrases, sentences and paragraphs are indicated by the presence of phrase, sentence and paragraph identifier characters in the data string, a given identifier character being taken to imply all lower-level identifiers as well (since e.g. every paragraph beginning is also a sentence and phrase beginning). The data string is read into the main store in such a way that no memory word contains more than one identifier character and that this, if present, occupies the lowest character position in the word. Any gaps necessitated by this rule are filled with null characters. The auxiliary store consists of a number of 2-dimensional magnetic core matrices, one for each hierarchical level and each having one bit position for each word of the main store at a corresponding address (the main and auxiliary stores use the same addressing means). During read-in of the data string into the main store, the identifier characters are recognized and the auxiliary store controlled so that if a given identifier is put into a particular word location in the main store, a ONE bit (the occurrence mark) is put into the corresponding address in the auxiliary store matrix associated with that identifier (i.e. hierarchical level) and also into all lower-level auxiliary store matrices. Selection of data for read-out from the main store is done by a specification, such as, for example, " third phrase of the second sentence of the fourth paragraph before/after address X." The contents of the paragraph auxiliary store are read out one row at a time and the ONE bits occurring in the specified direction from address X are counted, until (in the above instance) four have been counted when, starting at the address thus reached, the procedure is repeated with the contents of the sentence store read out one row at a time for this purpose, and so on until the address of the beginning (or end, depending on direction) of the required phrase is obtained. The next phrase occurrence mark is then located to give the end or beginning respectively of the phrase. The absolute addresses of the beginning and end of the required phrase thus obtained are used for reading the phrase out of main store. Full conventional circuitry to achieve the above is shown and described.

Title: Improvements in or relating to mechanism for presenting rotation of a first member relative to a second member, e.g., in a displacement indicator
IPC: B23Q15/22
Filed: 1955-07-20
Abstract: 785,245. Machine-tool details. GIDDINGS & LEWIS MACHINE TOOL CO. July 20, 1955 [July 28, 1954], No. 21003/55. Class 83 (3). [Also in Group XXIV] An indicator for measuring the linear displacement of a translatable member, e.g. the tool or work-holder of a machine-tool, or the angular displacement of a rotatable member, comprises a shaft 10 j ournalled by a bearing 11 in the housing 12 of equipment in which the indicator is used, and having secured thereto a gear 14 driven by the member whose displacement is to be measured. Fixed to the shaft by a key 25 are a pinion 40 and a flange 24 supporting an annular dial 15. Pinion 40 drives a number of floating pinions 41 which mesh with a member 42 fixed to housing 12, an annular dial 19, and a ring 18. Member 42 and ring 18 each have the same number of teeth so that ring 18 is held stationary during rotation-of the pinions, whereas dial 19 has at least one extra tooth so that it is turned in timed relation to shaft 10. Flanged members 48 within pinions 41 contain spring-pressed balls 49 to urge flange 24 and a member 22 secured thereto against a shoulder 21 on the shaft, and also to urge the members 42, 19, 18 towards the housing. Dial 19 may be graduated, e.g. to record a displacement of 39 inches in divisions of 1/ 5  inch, whereas dial 15 may have 200 divisions each of <SP>1</SP>/ 1000  inch, and the dials are read against a mark 16 on ring 18. A counterweight 20 is journalled in shaft 10 and connected by gears 36, 38 to the dial 15, so that rotation of the weight in one direction causes rotation of the dial in the opposite direction relatively to members 24, 22, and the dial may be set or indexed relatively to shaft 10. In order to prevent rotation of the dial 15 relatively to the shaft when the latter is driven, the moment of inertia of counterweight 20 is so arranged that when multiplied by the mechanical advantage of the gear drive, it equals the moment of inertia of dial 15. Thus during acceleration or deceleration of the shaft both members 15, 20 will tend to rotate in the same direction due to inertia forces which oppose and counterbalance one another.
